Test chi-kvadr\u00e1t, zn\u00e1m\u00fd v aplikac\u00edch Microsoft Excel a Google Sheets jako CHISQ.TEST, je pou\u017e\u00edv\u00e1n k ur\u010den\u00ed, zda jsou rozd\u00edly mezi o\u010dek\u00e1van\u00fdmi a pozorovan\u00fdmi frekvencemi v kategori\u00e1ln\u00edch datech statisticky v\u00fdznamn\u00e9. Tento test je kl\u00ed\u010dov\u00fdm analytick\u00fdm n\u00e1strojem pro hodnocen\u00ed nez\u00e1vislosti v kontingen\u010dn\u00edch tabulk\u00e1ch.<\/p>\n
